Answer:
See attached diagram
Step-by-step explanation:
Graph the solution of the inequality 
First, draw the dotted line 
(dotted because the sign of the inequality is <). Then determine wich part of the coordinate plane should be shaded. Since the origin's coordinates satisfy the inequality, then this point should belong to the region (red part on the diagram).
Graph the solution of the inequality 
First, draw the solid line 
(solid because the sign of the inequality is ≥). Then determine wich part of the coordinate plane should be shaded. Since the origin's coordinates satisfy the inequality, then this point should belong to the region (blue part on the diagram).
The intersection of both regions is the solution of the system of two inequalities.
Answer:
C) The mean is about 100.
Step-by-step explanation:
We see that the best fit line (out of the options listed) would be y=100. The mean can also be algebraically calculated with the following equation:
Let 
be the mean (average) of the values:
, which is closest to answer choice C) The mean is about 100.
The angles of a triangle are right angles
90 = 1/3x + 8
82 = 1/3x
246 = x
Answer is B
Answer:
The correct answer is option <em>B. AA</em>
<em></em>
Step-by-step explanation:
Given two triangle:
and 
.
The dimensions given in are:
We know that the sum of three angles in a triangle is equal to 
.
The dimensions given in are:
We know that the sum of three angles in a triangle is equal to .
Now, if we compare the angles of the two triangles:
So, by AA postulate (i.e. Angle - Angle) postulate, the two triangles are similar.
by <em>AA theorem.</em>
<em>So, correct answer is option B. AA </em>
X square + 1x + 4x + 4
X(x+1)+4(x+1)
(X+1)(x+4)
